Stripped the top of my Mercer Kilo TT seatpost?
I was out for a ride and my saddle kept slipping to the right, so I went home to tighten my seat tube clamp, but it turns out that the top of my seatpost is just spinning in place. I guess the clamp area actually threads into the seatpost. Has anyone else had this problem? Also just double checking that I'm going to need a 26.8mm seatpost as a replacement. Thanks!
